Any change to share the example file so other can try to reproduce it easily (and of course investigate the source of the issue)

Kompi's PNG result

There are some white lines (it are borders between bitmaps) but they are too thin, I checked in

Reproducible on current stable and master builds. 

Not reproducible on v.3.3, therefore it is a regression. 

I could reproduce on 5.4.0.0.alpha (displays very faint lines if you zoom in), but strangely enough, not on 6.3.0.0.alpha or 6.4.0.0.alpha.

Skia enabled vs disabled

Bibisected with win64-7.0. Dev who made the commit looks to be inactive. 

Interestingly, seems to be Skia related. There looks to be a difference in quality when Skia is enabled vs. disabled (via Tools > Options > View > Use Skia for all rendering)

Dear karl-heinz.behr@nway.de,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
 
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword


Feel free to come ask questions or to say hello in our QA chat: https://web.libera.chat/?settings=#libreoffice-qa

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team
